ここで使用される立体化学の定義および取り決めは、一般にMcGraw-Hill Dictionary of Chemical Terms, S. P. Parker, Ed., McGraw-Hill Book Company, New York (1984) ならびにStereochemistry of Organic Compounds, Eliel, E. and Wilen, S., John Wiley & Sons, Inc., New York (1994)に従う。多くの有機化合物は光学活性型として存在する。即ち、これらは平面偏光光の平面を回転させる能力を有している。光学活性化合物を記述するとき、符号DおよびLあるいはRおよびSはそのキラル中心についての分子の絶対的配置を示すために使用される。符号dおよびlあるいは(+)および(−)はその化合物による平面偏光光の回転態様を示すために用いられ、(−)あるいはlはその化合物が左旋であることを、そして(+)あるいはdは右旋性であることを意味する。与えられた化学構造において、これらの立体異性体と呼ばれる化合物は、これらが互いに鏡面像を呈することを別にして同一である。鏡面像対の特定立体異性体をエナンチオマーといい、これら異性体混合物はしばしばエナンチオマー混合体と呼ばれている。

反応式1:
好ましいα−アミノ保護基はBocまたはFmocの何れかである。ペプチド合成のために適切に保護された多くのアミノ酸誘導体が市場で入手できる。新たに添加されたアミノ酸残基のα−アミノ保護基は、次のアミノ酸のカップリングに先立って開裂される。Bocを用いた場合、選択される方法は、それ自体もしくはジクロロメタン中のトリフルオロ酢酸、またはジオキサンあるいは酢酸エチル中のHClである。生成アンモニウム塩は次いでカップリング反応の前あるいはこれと同時にバッファー水溶液あるいはジクロロメタンあるいはアセトニトリル中の三級アミンあるいはジメチルフォルムアミドのような塩基性溶液で中和される。Foc基を用いた場合、選択される試薬はジメチルフォルムアミド中のピペリジンあるいは置換ピペリジンであるが、二級アミンはすべて使用できる。脱保護反応は、0℃から通常20−22℃である室温(rtあるいはRT)の範囲で行われる。
R4O-C(O)-の化合物の製造に際しては、保護されたP3あるいは全ペプチドあるいはペプチドセグメントは適当なクロロフォーメートとカップリングされ、これらは市販品として入手可能であるか、あるいはその合成法が当分野でよく知られたものである。
Boc誘導体については(Boc)2Oが使用される。
例えば、
クロロフォルメートはトリエチルアミンのような塩基の存在下に所望のNH2−トリペプチドで処理されて、シクロペンチルカルバメートを与える。

生化学的研究
組換えHCV NS3/4Aプロテアーゼ複合体FRETペプチドアッセイ
このインビトロアッセイの目的は、以下に説明するBMS、H77CまたはJ416S株由来のHCV NS3プロテアーゼ複合体が本発明の化合物から受ける阻害を測定することだった。このアッセイにより、HCVタンパク質分解活性の阻害に関して本発明の化合物がどの程度有効であるかの指標が得られる。
100-[(δFinh/δFcon)×100]
[式中、δFは曲線の線形領域での蛍光の変化である]。Excel XLfitソフトウェアを使用し、式:y=A+((B-A)/(1+((C/x)^D)))を使って、阻害-濃度データに非線形カーブフィッティングを行い、50%有効濃度(IC50)を計算した。
HCV NS3/4Aプロテアーゼの阻害に関して、他のセリンプロテアーゼまたはシステインプロテアーゼとの比較で、本発明化合物の選択性を実証するために、特異性アッセイを行った。

を使って計算した。
Lohmann V,Korner F,Koch J,Herian U,Theilmann L,Bartenschlager R.,Science 285(5424):110-3(1999)に記載されているように、HCVレプリコン全細胞系を樹立した。この系により、本発明者らのHCVプロテアーゼ化合物がHCV RNA複製に及ぼす影響を評価することができるようになった。簡単に述べると、Lohmannの報文に記載されているHCV 1B株配列(アクセッション番号:AJ238799)を使って、5'内部リボソーム結合部位(IRES)、ネオマイシン耐性遺伝子、EMCV(脳心筋炎ウイルス)-IRESおよびHCV非構造タンパク質NS3〜NS5Bならびに3'非翻訳領域(NTR)をコードするHCV cDNAを作製した。このcDNAのインビトロ転写物をヒト肝細胞癌細胞系Huh7にトランスフェクトした。選択マーカー、ネオマイシン(G418)の存在下で、上記HCVレプリコンを構成的に発現させる細胞を選択した。得られた細胞株を、プラス鎖およびマイナス鎖RNA鎖産生ならびにタンパク質産生に関して、経時的に特徴づけた。
対照に対する%=[実験ウェルでの平均ルシフェラーゼシグナル(+化合物)]/[DMSO対照ウェルでの平均ルシフェラーゼシグナル(−化合物)]。
XLfitを使って値のグラフ化と解析を行うことにより、EC50値を求めた。
HCVレプリコン細胞アッセイおよび/または概説した特異性アッセイのいくつかで、代表的な本発明化合物を評価した。例えば化合物8は、酵素アッセイでは、NS3/4A BMS株に対して51nMのIC50を持つことがわかった。公表されているH77C株(11nMのIC50)およびJ4L6S株(9.5nMのIC50)でも、同様の効力値が得られた。レプリコンアッセイでのEC50値は284nMだった。
IC50活性範囲:A>10マイクロモル(μM)、Bは1〜10μM、Cは0.1〜1μM、D<0.1μM。
EC50活性範囲:A>10マイクロモル(μM)、Bは1〜10μM、Cは0.1〜1μM、D<0.1μM。
